Nextel, the fifth largest mobile-phone company in the United States, offers its customersunique technology that combines a variety of wireless services on one handset. Despite its

dominance in the business market and its high revenue growth, through early 2002 the companywas still in a net-loss position. Its continued march toward profitability requires large capitalexpenditures; in 2000 alone, it spent $3.5 billion to keep up with technological advances and addnew features. To fund its growth, Nextel raised well over $20 billion in new debt and equity financ-ing from 1996 to 2000.

Searching for new sources of capital and finding the most appropriate sources for differentpurposes can keep costs of capital in line. Nextel aggressively raises capital whenever it sees anopportunity, so that money will always be available for expansion. The firm combines differentfinancing instruments to create a healthy balance between debt and equity. The type of financingis tied to market conditions. When the high-yield debt markets tightened in 1998 as a conse-quence of the international financial situation, the private markets proved to be a better, morereasonably priced choice. The company also issued convertible bonds and preferred stock whenmarket conditions were right. In 2000 Nextel was able to tap strong equity markets to issue $2.8billion of common equity, which helped it to stay within existing debt provisions. This turned out tobe a good move; the market for telecommunications and other technology stocks collapsed soonafter.

Choosing cost-effective financing instruments so that Nextel can work toward a balancedcapital structure is no easy task in today’s volatile capital markets. If the equity markets areclosed, the company may have no choice but to issue debt, regardless of cost, in order to secureadequate funding for its capital projects.

In this chapter we’ll demonstrate how to calculate the cost of specific sources of capitaland how to combine them to arrive at a weighted cost of capital that firms can use to evaluateinvestment opportunities.

470 PART 4 Long-Term Financial Decisions

11.1 An Overview of the Cost of CapitalThe cost of capital is the rate of return that a firm must earn on the projects inwhich it invests to maintain the market value of its stock. It can also be thoughtof as the rate of return required by the market suppliers of capital to attract theirfunds to the firm. If risk is held constant, projects with a rate of return above thecost of capital will increase the value of the firm, and projects with a rate ofreturn below the cost of capital will decrease the value of the firm.

The cost of capital is an extremely important financial concept. It acts as amajor link between the firm’s long-term investment decisions (discussed in Part3) and the wealth of the owners as determined by investors in the marketplace.It is in effect the “magic number” that is used to decide whether a proposedcorporate investment will increase or decrease the firm’s stock price. Clearly,only those investments that are expected to increase stock price (NPV�$0, orIRR�cost of capital) would be recommended. Because of its key role in fi-nancial decision making, the importance of the cost of capital cannot beoveremphasized.

Some Key AssumptionsThe cost of capital is a dynamic concept affected by a variety of economic andfirm-specific factors. To isolate the basic structure of the cost of capital, we makesome key assumptions relative to risk and taxes:

1. Business risk—the risk to the firm of being unable to cover operating costs—is assumed to be unchanged. This assumption means that the firm’s accep-tance of a given project does not affect its ability to meet operating costs.

2. Financial risk—the risk to the firm of being unable to cover required finan-cial obligations (interest, lease payments, preferred stock dividends)—isassumed to be unchanged. This assumption means that projects are financedin such a way that the firm’s ability to meet required financing costs isunchanged.

3. After-tax costs are considered relevant. In other words, the cost of capital ismeasured on an after-tax basis. This assumption is consistent with the frame-work used to make capital budgeting decisions.

The Basic ConceptThe cost of capital is estimated at a given point in time. It reflects the expectedaverage future cost of funds over the long run. Although firms typically raisemoney in lumps, the cost of capital should reflect the interrelatedness of financingactivities. For example, if a firm raises funds with debt (borrowing) today, it islikely that some form of equity, such as common stock, will have to be used thenext time it needs funds. Most firms attempt to maintain a desired optimal mix ofdebt and equity financing. This mix is commonly called a target capitalstructure—a topic that will be addressed in Chapter 12. Here, it is sufficient to

Hint Because of the positiverelationship between risk andreturn, a firm’s financing cost(cost of capital) will change ifthe acceptance of a projectchanges the firm’s business orfinancial risk. The cost ofcapital can therefore be moreeasily measured by assumingthat new projects do not changethese risks.

say that although firms raise money in lumps, they tend toward some desired mixof financing.

To capture the interrelatedness of financing assuming the presence of a targetcapital structure, we need to look at the overall cost of capital rather than thecost of the specific source of funds used to finance a given expenditure.

E X A M P L E A firm is currently faced with an investment opportunity. Assume the following:

Best project available today

Cost�$100,000Life�20 yearsIRR�7%

Cost of least-cost financing source available

Debt�6%

Because it can earn 7% on the investment of funds costing only 6%, the firmundertakes the opportunity. Imagine that 1 week later a new investment opportu-nity is available:

Best project available 1 week later

Cost�$100,000Life�20 yearsIRR�12%

Cost of least-cost financing source available

Equity�14%

In this instance, the firm rejects the opportunity, because the 14% financing costis greater than the 12% expected return.

Were the firm’s actions in the best interests of its owners? No; it accepted aproject yielding a 7% return and rejected one with a 12% return. Clearly, thereshould be a better way, and there is: The firm can use a combined cost, whichover the long run will yield better decisions. By weighting the cost of each sourceof financing by its target proportion in the firm’s capital structure, the firm canobtain a weighted average cost that reflects the interrelationship of financingdecisions. Assuming that a 50–50 mix of debt and equity is targeted, the weightedaverage cost here would be 10% [(0.50�6% debt)� (0.50�14% equity)]. Withthis cost, the first opportunity would have been rejected (7% IRR�10%weighted average cost), and the second would have been accepted (12% IRR�10% weighted average cost). Such an outcome would clearly be more desirable.

The Cost of Specific Sources of CapitalThis chapter focuses on finding the costs of specific sources of capital and com-bining them to determine the weighted average cost of capital. Our concern isonly with the long-term sources of funds available to a business firm, becausethese sources supply the permanent financing. Long-term financing supports the


firm’s fixed-asset investments.1 We assume throughout the chapter that suchinvestments are selected by using appropriate capital budgeting techniques.

There are four basic sources of long-term funds for the business firm: long-term debt, preferred stock, common stock, and retained earnings. The right-handside of a balance sheet can be used to illustrate these sources:

Although not every firm will use all of these methods of financing, each firm isexpected to have funds from some of these sources in its capital structure.

The specific cost of each source of financing is the after-tax cost of obtainingthe financing today, not the historically based cost reflected by the existingfinancing on the firm’s books. Techniques for determining the specific cost ofeach source of long-term funds are presented on the following pages. Althoughthese techniques tend to develop precisely calculated values, the resulting valuesare at best rough approximations because of the numerous assumptions and fore-casts that underlie them. Although we round calculated costs to the nearest 0.1percent throughout this chapter, it is not unusual for practicing financial man-agers to use costs rounded to the nearest 1 percent because these values are merelyestimates.

1. The role of both long-term and short-term financing in supporting both fixed- and current-asset investments isaddressed in Chapter 14. Suffice it to say that long-term funds are at minimum used to finance fixed assets.

11.2 The Cost of Long-Term DebtThe cost of long-term debt, ki, is the after-tax cost today of raising long-termfunds through borrowing. For convenience, we typically assume that the funds areraised through the sale of bonds. In addition, as we did in Chapter 6, we assumethat the bonds pay annual (rather than semiannual) interest.

Net ProceedsMost corporate long-term debts are incurred through the sale of bonds. The netproceeds from the sale of a bond, or any security, are the funds that are actuallyreceived from the sale. Flotation costs—the total costs of issuing and selling asecurity—reduce the net proceeds from the sale. These costs apply to all publicofferings of securities—debt, preferred stock, and common stock. They includetwo components: (1) underwriting costs—compensation earned by investmentbankers for selling the security, and (2) administrative costs—issuer expensessuch as legal, accounting, printing, and other expenses.

E X A M P L E Duchess Corporation, a major hardware manufacturer, is contemplating selling$10 million worth of 20-year, 9% coupon (stated annual interest rate) bonds,each with a par value of $1,000. Because similar-risk bonds earn returns greaterthan 9%, the firm must sell the bonds for $980 to compensate for the lowercoupon interest rate. The flotation costs are 2% of the par value of the bond(0.02�$1,000), or $20. The net proceeds to the firm from the sale of each bondare therefore $960 ($980�$20).

Before-Tax Cost of DebtThe before-tax cost of debt, kd, for a bond can be obtained in any of three ways:quotation, calculation, or approximation.

Using Cost Quotations

When the net proceeds from sale of a bond equal its par value, the before-tax costjust equals the coupon interest rate. For example, a bond with a 10 percentcoupon interest rate that nets proceeds equal to the bond’s $1,000 par valuewould have a before-tax cost, kd, of 10 percent.

A second quotation that is sometimes used is the yield to maturity (YTM) ona similar-risk bond2 (see Chapter 6). For example, if a similar-risk bond has aYTM of 9.7 percent, this value can be used as the before-tax cost of debt, kd.

Calculating the Cost

This approach finds the before-tax cost of debt by calculating the internal rate ofreturn (IRR) on the bond cash flows. From the issuer’s point of view, this valueis the cost to maturity of the cash flows associated with the debt. The cost to

maturity can be calculated by using either a trial-and-error technique3 or a finan-cial calculator. It represents the annual before-tax percentage cost of the debt.

E X A M P L E In the preceding example, the net proceeds of a $1,000, 9% coupon interest rate,20-year bond were found to be $960. The calculation of the annual cost is quitesimple. The cash flow pattern is exactly the opposite of a conventional pattern; itconsists of an initial inflow (the net proceeds) followed by a series of annual out-lays (the interest payments). In the final year, when the debt is retired, an outlayrepresenting the repayment of the principal also occurs. The cash flows associ-ated with Duchess Corporation’s bond issue are as follows:

End of year(s) Cash flow

1–20 �$ 90

In Practice

In August 2000, Dow Chemicalbecame the first industrial corpo-ration to price and distribute bondsonline. WR Hambrecht � Co., apioneer in online equity IPOs, con-ducted the 2-hour Dutch auction atits OpenBook auction Web site. Ina Dutch auction (long used to priceand sell Treasury bonds), investorsplace bids to buy a particularamount of a security at a specificprice within a spread set by theissuer before the auction. Theunderwriter accepts the lowestprice at which there is enoughdemand to sell all the bondsoffered (the clearing price).Investors who bid that price orhigher get their requested alloca-tions at the clearing price.

Dow’s open bond auction of$300 million in 5-year bonds waswell received, attracting a broaderinvestor base that could reducevolatility in the secondary market.

The interest rate on the issue wassimilar to what Dow would havepaid using the traditional syndica-tion process, but the underwritingfee was over 50 percent lower. “Tome, it’s a no-brainer,” said Dowtreasurer Geoffery Merszei.

In the future, market watch-ers expect Internet auctions tolower issuance costs for debt cap-ital through more efficient pricingthat reflects market demand. Allbidders have equal access tosecurities, and investors can see areal-time, fully visible demandcurve for a bond issue as itunfolds, resulting in improved dis-tribution and enhanced liquidity.

Despite Dow’s success, fewcorporations have followed itonline. Ford Motor Credit issued$750 million of 3-year notes inMarch 2001. In February 2001,government-sponsored residentialmortgage agency Freddie Mac

announced that it would use Open-Book for eight auctions. So far,most major investment bankershave resisted endorsing a methodthat would undercut their morelucrative traditional underwritingbusiness. However, both propo-nents and opponents of onlineDutch auctions of corporate debtbelieve that this method worksbest for large, standard-issuebonds from investment-gradeissuers.

The initial $960 inflow is followed by annual interest outflows of $90 (9%coupon interest rate�$1,000 par value) over the 20-year life of the bond. In year20, an outflow of $1,000 (the repayment of the principal) occurs. We can deter-mine the cost of debt by finding the IRR, which is the discount rate that equatesthe present value of the outflows to the initial inflow.

Calculator Use [Note: Most calculators require either the present (net proceeds)or the future (annual interest payments and repayment of principal) values to beinput as negative numbers when we calculate cost to maturity. That approach isused here.] Using the calculator and the inputs shown at the left, you should findthe before-tax cost (cost to maturity) to be 9.452%.

Approximating the Cost

The before-tax cost of debt, kd, for a bond with a $1,000 par value can beapproximated by using the following equation:

This approximate before-tax cost of debt is close to the 9.452% value calculatedprecisely in the preceding example.

After-Tax Cost of DebtHowever, as indicated earlier, the specific cost of financing must be stated onan after-tax basis. Because interest on debt is tax deductible, it reduces thefirm’s taxable income. The after-tax cost of debt, ki, can be found by multiply-ing the before-tax cost, kd, by 1 minus the tax rate, T, as stated in the followingequation:

Input Function


E X A M P L E Duchess Corporation has a 40% tax rate. Using the 9.4% before-tax debt costcalculated above, and applying Equation 11.2, we find an after-tax cost of debtof 5.6% [9.4%� (1�0.40)]. Typically, the explicit cost of long-term debt is lessthan the explicit cost of any of the alternative forms of long-term financing, pri-marily because of the tax deductibility of interest.

11.3 The Cost of Preferred StockPreferred stock represents a special type of ownership interest in the firm. It givespreferred stockholders the right to receive their stated dividends before any earn-ings can be distributed to common stockholders. Because preferred stock is aform of ownership, the proceeds from its sale are expected to be held for an infi-nite period of time. The key characteristics of preferred stock were described inChapter 7. However, the one aspect of preferred stock that requires review isdividends.

Preferred Stock DividendsMost preferred stock dividends are stated as a dollar amount: “x dollars peryear.” When dividends are stated this way, the stock is often referred to as “x-dollar preferred stock.” Thus a “$4 preferred stock” is expected to pay preferredstockholders $4 in dividends each year on each share of preferred stock owned.

Sometimes preferred stock dividends are stated as an annual percentage rate.This rate represents the percentage of the stock’s par value, or face value, thatequals the annual dividend. For instance, an 8 percent preferred stock with a $50par value would be expected to pay an annual dividend of $4 a share (0.08�$50par�$4). Before the cost of preferred stock is calculated, any dividends stated aspercentages should be converted to annual dollar dividends.

Calculating the Cost of Preferred StockThe cost of preferred stock, kp, is the ratio of the preferred stock dividend to thefirm’s net proceeds from the sale of the preferred stock. The net proceeds repre-sents the amount of money to be received minus any flotation costs. Equation11.3 gives the cost of preferred stock, kp, in terms of the annual dollar dividend,Dp, and the net proceeds from the sale of the stock, Np:

kp � (11.3)Dp�Np

cost of preferred stock, kpThe ratio of the preferred stockdividend to the firm’s netproceeds from the sale ofpreferred stock; calculated bydividing the annual dividend, Dp ,by the net proceeds from the saleof the preferred stock, Np.

LG2

Because preferred stock dividends are paid out of the firm’s after-tax cash flows,a tax adjustment is not required.

E X A M P L E Duchess Corporation is contemplating issuance of a 10% preferred stock that isexpected to sell for its $87-per-share par value.4 The cost of issuing and sellingthe stock is expected to be $5 per share. The first step in finding the cost of thestock is to calculate the dollar amount of the annual preferred dividend, which is$8.70 (0.10�$87). The net proceeds per share from the proposed sale of stockequals the sale price minus the flotation costs ($87�$5�$82). Substituting theannual dividend, Dp, of $8.70 and the net proceeds, Np, of $82 into Equation11.3 gives the cost of preferred stock, 10.6% ($8.70$82).

The cost of Duchess’s preferred stock (10.6%) is much greater than the costof its long-term debt (5.6%). This difference exists primarily because the cost oflong-term debt (the interest) is tax deductible.

11–8 How would you calculate the cost of preferred stock?

11.4 The Cost of Common StockThe cost of common stock is the return required on the stock by investors in themarketplace. There are two forms of common stock financing: (1) retained earn-ings and (2) new issues of common stock. As a first step in finding each of thesecosts, we must estimate the cost of common stock equity.

Finding the Cost of Common Stock EquityThe cost of common stock equity, ks, is the rate at which investors discount theexpected dividends of the firm to determine its share value. Two techniques areused to measure the cost of common stock equity.5 One relies on the constant-growth valuation model, the other on the capital asset pricing model (CAPM).

Using the Constant-Growth Valuation (Gordon) Model

In Chapter 7 we found the value of a share of stock to be equal to the present valueof all future dividends, which in one model were assumed to grow at a constantannual rate over an infinite time horizon. This is the constant-growth valuation

cost of common stock equity, ksThe rate at which investorsdiscount the expected dividendsof the firm to determine its sharevalue.

4. For simplicity, the preferred stock in this example is assumed to be sold for its par value. In practice, particularlyfor subsequent issues of already outstanding preferred stock, it is typically sold at a price that differs from its parvalue.5. Other, more subjective techniques are available for estimating the cost of common stock equity. One populartechnique is the bond yield plus a premium; it estimates the cost of common stock equity by adding a premium, typ-ically between 3% and 5%, to the firm’s current cost of long-term debt. Another, even more subjective techniqueuses the firm’s expected return on equity (ROE) as a measure of its cost of common stock equity. Here we focus onlyon the more theoretically based techniques.

model, also known as the Gordon model. The key expression derived for thismodel was presented as Equation 7.5 and is restated here:

P0 � (11.4)

where

P0 �value of common stockD1 �per-share dividend expected at the end of year 1ks � required return on common stockg�constant rate of growth in dividends

Solving Equation 11.4 for ks results in the following expression for the costof common stock equity:

ks � �g (11.5)

Equation 11.5 indicates that the cost of common stock equity can be found bydividing the dividend expected at the end of year 1 by the current price of thestock and adding the expected growth rate. Because common stock dividends arepaid from after-tax income, no tax adjustment is required.

E X A M P L E Duchess Corporation wishes to determine its cost of common stock equity, ks.The market price, P0, of its common stock is $50 per share. The firm expects topay a dividend, D1, of $4 at the end of the coming year, 2004. The dividends paidon the outstanding stock over the past 6 years (1998–2003) were as follows:

Using the table for the present value interest factors, PVIF (Table A–2), or afinancial calculator in conjunction with the technique described for findinggrowth rates in Chapter 4, we can calculate the annual growth rate of dividends,g. It turns out to be approximately 5% (more precisely, it is 5.05%). SubstitutingD1 �$4, P0 �$50, and g�5% into Equation 11.5 yields the cost of commonstock equity:

ks � � 0.05�0.08�0.05�0.130, or 1��3��.��0��%

The 13.0% cost of common stock equity represents the return required by exist-ing shareholders on their investment. If the actual return is less than that, share-holders are likely to begin selling their stock.

Using the Capital Asset Pricing Model (CAPM)

Recall from Chapter 5 that the capital asset pricing model (CAPM) describes therelationship between the required return, ks, and the nondiversifiable risk of thefirm as measured by the beta coefficient, b. The basic CAPM is

ks �RF � [b� (km �RF)] (11.6)

where

RF � risk-free rate of returnkm �market return; return on the market portfolio of assets

Using CAPM indicates that the cost of common stock equity is the returnrequired by investors as compensation for the firm’s nondiversifiable risk, mea-sured by beta.

E X A M P L E Duchess Corporation now wishes to calculate its cost of common stock equity,ks, by using the capital asset pricing model. The firm’s investment advisers andits own analyses indicate that the risk-free rate, RF, equals 7%; the firm’s beta,b, equals 1.5; and the market return, km, equals 11%. Substituting these valuesinto Equation 11.6, the company estimates the cost of common stock equity, ks,to be

ks �7.0%� [1.5� (11.0%�7.0%)]�7.0%�6.0%�1��3��.��0��%

The 13.0% cost of common stock equity represents the required return of investorsin Duchess Corporation common stock. It is the same as that found by using theconstant-growth valuation model.

Comparing the Constant-Growth and CAPM Techniques

The CAPM technique differs from the constant-growth valuation model in that itdirectly considers the firm’s risk, as reflected by beta, in determining the requiredreturn or cost of common stock equity. The constant-growth model does not lookat risk; it uses the market price, P0, as a reflection of the expected risk–return pref-erence of investors in the marketplace. The constant-growth valuation andCAPM techniques for finding ks are theoretically equivalent. But it is difficult todemonstrate that equivalency because of measurement problems associated withgrowth, beta, the risk-free rate (what maturity of government security to use), andthe market return. The use of the constant-growth valuation model is often pre-ferred because the data required are more readily available.

Another difference is that when the constant-growth valuation model is usedto find the cost of common stock equity, it can easily be adjusted for flotationcosts to find the cost of new common stock; the CAPM does not provide a simpleadjustment mechanism. The difficulty in adjusting the cost of common stockequity calculated by using CAPM occurs because in its common form the modeldoes not include the market price, P0, a variable needed to make such an adjust-ment. Although CAPM has a stronger theoretical foundation, the computationalappeal of the traditional constant-growth valuation model justifies its usethroughout this text to measure common stock costs.

The Cost of Retained EarningsAs you know, dividends are paid out of a firm’s earnings. Their payment, madein cash to common stockholders, reduces the firm’s retained earnings. Let’s say afirm needs common stock equity financing of a certain amount; it has two choicesrelative to retained earnings: It can issue additional common stock in thatamount and still pay dividends to stockholders out of retained earnings. Or it canincrease common stock equity by retaining the earnings (not paying the cash div-idends) in the needed amount. In a strict accounting sense, the retention of earn-ings increases common stock equity in the same way that the sale of additionalshares of common stock does. Thus the cost of retained earnings, kr , to the firmis the same as the cost of an equivalent fully subscribed issue of additional com-mon stock. Stockholders find the firm’s retention of earnings acceptable only ifthey expect that it will earn at least their required return on the reinvested funds.

Viewing retained earnings as a fully subscribed issue of additional commonstock, we can set the firm’s cost of retained earnings, kr, equal to the cost of com-mon stock equity as given by Equations 11.5 and 11.6.6

kr �ks (11.7)

It is not necessary to adjust the cost of retained earnings for flotation costs, becauseby retaining earnings, the firm “raises” equity capital without incurring these costs.

E X A M P L E The cost of retained earnings for Duchess Corporation was actually calculated inthe preceding examples: It is equal to the cost of common stock equity. Thus krequals 13.0%. As we will show in the next section, the cost of retained earnings isalways lower than the cost of a new issue of common stock, because it entails noflotation costs.

The Cost of New Issues of Common StockOur purpose in finding the firm’s overall cost of capital is to determine the after-tax cost of new funds required for financing projects. The cost of a new issue ofcommon stock, kn, is determined by calculating the cost of common stock, net ofunderpricing and associated flotation costs. Normally, for a new issue to sell, ithas to be underpriced—sold at a price below its current market price, P0.

Firms underprice new issues for a variety of reasons. First, when the marketis in equilibrium (that is, the demand for shares equals the supply of shares),additional demand for shares can be achieved only at a lower price. Second, whenadditional shares are issued, each share’s percent of ownership in the firm isdiluted, thereby justifying a lower share value. Finally, many investors view theissuance of additional shares as a signal that management is using common stockequity financing because it believes that the shares are currently overpriced. Rec-ognizing this information, they will buy shares only at a price below the currentmarket price. Clearly, these and other factors necessitate underpricing of new

6. Technically, if a stockholder received dividends and wished to invest them in additional shares of the firm’s stock,he or she would first have to pay personal taxes on the dividends and then pay brokerage fees before acquiring addi-tional shares. By using pt as the average stockholder’s personal tax rate and bf as the average brokerage fees statedas a percentage, we can specify the cost of retained earnings, kr, as kr �ks � (1�pt)� (1�bf). Because of the diffi-culty in estimating pt and bf, only the simpler definition of kr given in Equation 11.7 is used here.

cost of retained earnings, krThe same as the cost of anequivalent fully subscribed issueof additional common stock,which is equal to the cost ofcommon stock equity, ks.

Hint Using retainedearnings as a major source offinancing for capitalexpenditures does not giveaway control of the firm anddoes not dilute present earningsper share, as would occur ifnew common stock wereissued. However, the firm musteffectively manage retainedearnings, in order to produceprofits that increase futureretained earnings.


offerings of common stock. Flotation costs paid for issuing and selling the newissue will further reduce proceeds.

We can use the constant-growth valuation model expression for the cost ofexisting common stock, ks, as a starting point. If we let Nn represent the net pro-ceeds from the sale of new common stock after subtracting underpricing andflotation costs, the cost of the new issue, kn, can be expressed as follows:7

kn � �g (11.8)

The net proceeds from sale of new common stock, Nn, will be less than thecurrent market price, P0. Therefore, the cost of new issues, kn, will always begreater than the cost of existing issues, ks, which is equal to the cost of retainedearnings, kr. The cost of new common stock is normally greater than any otherlong-term financing cost. Because common stock dividends are paid from after-tax cash flows, no tax adjustment is required.

E X A M P L E In the constant-growth valuation example, we found Duchess Corporation’s costof common stock equity, ks, to be 13%, using the following values: an expecteddividend, D1, of $4; a current market price, P0, of $50; and an expected growthrate of dividends, g, of 5%.

To determine its cost of new common stock, kn, Duchess Corporation hasestimated that on the average, new shares can be sold for $47. The $3-per-shareunderpricing is due to the competitive nature of the market. A second cost associ-ated with a new issue is flotation costs of $2.50 per share that would be paid toissue and sell the new shares. The total underpricing and flotation costs per shareare therefore expected to be $5.50.

Subtracting the $5.50 per share underpricing and flotation cost from the cur-rent $50 share price results in expected net proceeds of $44.50 per share ($50.00�$5.50). Substituting D1 �$4, Nn �$44.50, and g�5% into Equation 11.8 resultsin a cost of new common stock, kn, as follows:

kn � �0.05�0.09�0.05�0.140, or 1��4��.��0��%

Duchess Corporation’s cost of new common stock is therefore 14.0%. This is thevalue to be used in subsequent calculations of the firm’s overall cost of capital.

11.5 The Weighted Average Cost of CapitalNow that we have calculated the cost of specific sources of financing, we candetermine the overall cost of capital. As noted earlier, the weighted average costof capital (WACC), ka, reflects the expected average future cost of funds over thelong run. It is found by weighting the cost of each specific type of capital by itsproportion in the firm’s capital structure.

Calculating the Weighted Average Cost of Capital (WACC)Calculating the weighted average cost of capital (WACC) is straightforward:Multiply the specific cost of each form of financing by its proportion in the firm’scapital structure and sum the weighted values. As an equation, the weighted aver-age cost of capital, ka, can be specified as follows:

ka � (wi �ki)� (wp �kp)� (ws �kr or n) (11.9)

where

wi �proportion of long-term debt in capital structurewp �proportion of preferred stock in capital structurews �proportion of common stock equity in capital structure

wi � wp � ws �1.0

Three important points should be noted in Equation 11.9:

1. For computational convenience, it is best to convert the weights into decimalform and leave the specific costs in percentage terms.

2. The sum of the weights must equal 1.0. Simply stated, all capital structurecomponents must be accounted for.

3. The firm’s common stock equity weight, ws, is multiplied by either the cost ofretained earnings, kr , or the cost of new common stock, kn. Which cost isused depends on whether the firm’s common stock equity will be financedusing retained earnings, kr , or new common stock, kn.

E X A M P L E In earlier examples, we found the costs of the various types of capital for DuchessCorporation to be as follows:

Cost of debt, ki � 5.6%Cost of preferred stock, kp �10.6%

Cost of retained earnings, kr �13.0%Cost of new common stock, kn �14.0%

The company uses the following weights in calculating its weighted average costof capital:

Because the firm expects to have a sizable amount of retained earnings avail-able ($300,000), it plans to use its cost of retained earnings, kr , as the cost ofcommon stock equity. Duchess Corporation’s weighted average cost of capital iscalculated in Table 11.1. The resulting weighted average cost of capital forDuchess is 9.8%. Assuming an unchanged risk level, the firm should accept allprojects that will earn a return greater than 9.8%.

Weighting SchemesWeights can be calculated on the basis of either book value or market value andusing either historical or target proportions.

Book Value Versus Market Value

Book value weights use accounting values to measure the proportion of each typeof capital in the firm’s financial structure. Market value weights measure the pro-portion of each type of capital at its market value. Market value weights areappealing, because the market values of securities closely approximate the actualdollars to be received from their sale. Moreover, because the costs of the varioustypes of capital are calculated by using prevailing market prices, it seems reason-able to use market value weights. In addition, the long-term investment cash

flows to which the cost of capital is applied are estimated in terms of current aswell as future market values. Market value weights are clearly preferred overbook value weights.

Historical Versus Target

Historical weights can be either book or market value weights based on actualcapital structure proportions. For example, past or current book value propor-tions would constitute a form of historical weighting, as would past or currentmarket value proportions. Such a weighting scheme would therefore be based onreal—rather than desired—proportions.

Target weights, which can also be based on either book or market values,reflect the firm’s desired capital structure proportions. Firms using target weightsestablish such proportions on the basis of the “optimal” capital structure theywish to achieve. (The development of these proportions and the optimal structureare discussed in detail in Chapter 12.)

When one considers the somewhat approximate nature of the calculation ofweighted average cost of capital, the choice of weights may not be critical. However,from a strictly theoretical point of view, the preferred weighting scheme is targetmarket value proportions, and these are assumed throughout this chapter.

11.6 The Marginal Cost and Investment DecisionsThe firm’s weighted average cost of capital is a key input to the investmentdecision-making process. As demonstrated earlier in the chapter, the firmshould make only those investments for which the expected return is greaterthan the weighted average cost of capital. Of course, at any given time, thefirm’s financing costs and investment returns will be affected by the volume offinancing and investment undertaken. The weighted marginal cost of capitaland the investment opportunities schedule are mechanisms whereby financingand investment decisions can be made simultaneously.

The Weighted Marginal Cost of Capital (WMCC)The weighted average cost of capital may vary over time, depending on the vol-ume of financing that the firm plans to raise. As the volume of financing increases,the costs of the various types of financing will increase, raising the firm’s weighted

average cost of capital. Therefore, it is useful to calculate the weighted marginalcost of capital (WMCC), which is simply the firm’s weighted average cost of cap-ital (WACC) associated with its next dollar of total new financing. This marginalcost is relevant to current decisions.

The costs of the financing components (debt, preferred stock, and commonstock) rise as larger amounts are raised. Suppliers of funds require greater returnsin the form of interest, dividends, or growth as compensation for the increasedrisk introduced by larger volumes of new financing. The WMCC is therefore anincreasing function of the level of total new financing.

Another factor that causes the weighted average cost of capital to increase isthe use of common stock equity financing. New financing provided by commonstock equity will be taken from available retained earnings until this supply isexhausted and then will be obtained through new common stock financing.Because retained earnings are a less expensive form of common stock equityfinancing than the sale of new common stock, the weighted average cost of capi-tal will rise with the addition of new common stock.

Finding Break Points

To calculate the WMCC, we must calculate break points, which reflect the levelof total new financing at which the cost of one of the financing components rises.The following general equation can be used to find break points:

BPj � (11.10)

where

BPj �break point for financing source jAFj �amount of funds available from financing source j at a given costwj �capital structure weight (stated in decimal form) for financing source j

E X A M P L E When Duchess Corporation exhausts its $300,000 of available retained earnings(at kr �13.0%), it must use the more expensive new common stock financing (atkn �14.0%) to meet its common stock equity needs. In addition, the firm expectsthat it can borrow only $400,000 of debt at the 5.6% cost; additional debt willhave an after-tax cost (ki) of 8.4%. Two break points therefore exist: (1) whenthe $300,000 of retained earnings costing 13.0% is exhausted, and (2) when the$400,000 of long-term debt costing 5.6% is exhausted.

The break points can be found by substituting these values and the corre-sponding capital structure weights given earlier into Equation 11.10. We get thedollar amounts of total new financing at which the costs of the given financingsources rise:

weighted marginal cost of capital (WMCC)The firm’s weighted average costof capital (WACC) associatedwith its next dollar of total newfinancing.


Calculating the WMCC

Once the break points have been determined, the next step is to calculate theweighted average cost of capital over the range of total new financing betweenbreak points. First, we find the WACC for a level of total new financing betweenzero and the first break point. Next, we find the WACC for a level of total newfinancing between the first and second break points, and so on. By definition, foreach of the ranges of total new financing between break points, certain compo-nent capital costs (such as debt or common equity) will increase. This will causethe weighted average cost of capital to increase to a higher level than that overthe preceding range.

Together, these data can be used to prepare a weighted marginal cost of cap-ital (WMCC) schedule. This is a graph that relates the firm’s weighted averagecost of capital to the level of total new financing.

E X A M P L E Table 11.2 summarizes the calculation of the WACC for Duchess Corporationover the three ranges of total new financing created by the two break points—$600,000 and $1,000,000. Comparing the costs in column 3 of the table for eachof the three ranges, we can see that the costs in the first range ($0 to $600,000)are those calculated in earlier examples and used in Table 11.1. The second range($600,000 to $1,000,000) reflects the increase in the common stock equity costto 14.0%. In the final range, the increase in the long-term debt cost to 8.4% isintroduced.

The weighted average costs of capital (WACC) for the three ranges are sum-marized in the table shown at the bottom of Figure 11.1. These data describe the

The Investment Opportunities Schedule (IOS)At any given time, a firm has certain investment opportunities available to it.These opportunities differ with respect to the size of investment, risk, and return.8The firm’s investment opportunities schedule (IOS) is a ranking of investment pos-sibilities from best (highest return) to worst (lowest return). Generally, the firstproject selected will have the highest return, the next project the second highest,and so on. The return on investments will decrease as the firm accepts additionalprojects.

A graph of the IOS for Duchess Corporation is given inFigure 11.2.



Using the WMCC and IOS to Make Financing/Investment DecisionsAs long as a project’s internal rate of return is greater than the weighted marginalcost of new financing, the firm should accept the project.9 The return willdecrease with the acceptance of more projects, and the weighted marginal cost ofcapital will increase because greater amounts of financing will be required. Thedecision rule therefore would be: Accept projects up to the point at which themarginal return on an investment equals its weighted marginal cost of capital.Beyond that point, its investment return will be less than its capital cost.10

This approach is consistent with the maximization of net present value (NPV)for conventional projects for two reasons: (1) The NPV is positive as long as theIRR exceeds the weighted average cost of capital, ka. (2) The larger the differencebetween the IRR and ka, the larger the resulting NPV. Therefore, the acceptanceof projects beginning with those that have the greatest positive difference between

9. Although net present value could be used to make these decisions, the internal rate of return is used here becauseof the ease of comparison it offers.10. So as not to confuse the discussion presented here, the fact that using the IRR for selecting projects may not yieldoptimal decisions is ignored. The problems associated with the use of IRR in capital rationing were discussed ingreater detail in Chapter 10.

In Practice

Do major U.S. corporations prac-tice what your professors teach?A recent survey of the cost of cap-ital techniques at Fortune 1000firms showed that financial man-agers today pay more attention tothe cost of capital and its role incapital budgeting and valuation ofthe firm than they did 15 years ago.A contributing factor is the grow-ing popularity of performanceevaluation models that use cost ofcapital in their formulas, such aseconomic value added (EVA®, dis-cussed in Chapter 9).

The survey, which updated astudy conducted in 1982, revealedthat companies are becomingmore sophisticated in their knowl-edge and use of financial tech-niques. Here are the key findingsfrom the 111 respondents, of whom41 percent were manufacturers, 46percent suppliers of services, and13 percent distributors.

• Most firms calculate the cost of capital using long-termdebt and equity, although someexclude capital leases and pre-ferred stock.

• Over 90 percent use aweighted average cost of capital(WACC); about half base the calcu-lation on target weights, another35 percent on current market valueweights.

• The current capital structureof most respondents is consistentwith their target capital structure.The average capital structure at thetime of the survey was 34 percentdebt, 5 percent preferred stock, and61 percent common stock.

• Firms use more than onemethod to calculate cost of equity;most employ the investors’required return, calculated usingCAPM.

• Over 60 percent of firms dif-ferentiate project risk on an indi-vidual project basis and adjust thediscount rate rather than cashflows.

• About half of the respondentsrecalculate their cost of capitalwhen environmental conditions(shifts in long-term rates) warrant;another 27 percent recompute itannually.

• Most firms use one cost ofcapital regardless of the totalamount of financing they require.Nearly all use the cost of capitalfor all new-project decisions; overthree-quarters use it to estimatethe firm’s value.

FOCUS ON PRACTICE Theory or Practice?


IRR and ka, down to the point at which IRR just equals ka, should result in themaximum total NPV for all independent projects accepted. Such an outcome iscompletely consistent with the firm’s goal of maximizing owner wealth.

E X A M P L E Figure 11.2 shows Duchess Corporation’s WMCC schedule and IOS on the sameset of axes. By raising $1,100,000 of new financing and investing these funds inprojects A, B, C, D, and E, the firm should maximize the wealth of its owners,because these projects result in the maximum total net present value. Note thatthe 12.0% return on the last dollar invested (in project E) exceeds its 11.5%weighted average cost. Investment in project F is not feasible, because its 11.0%return is less than the 11.5% cost of funds available for investment.

The firm’s optimal capital budget of $1,100,000 is marked with an X in Fig-ure 11.2. At that point, the IRR equals the weighted average cost of capital, andthe firm’s size as well as its shareholder value will be optimized. In a sense, thesize of the firm is determined by the market—the availability of and returns oninvestment opportunities, and the availability and cost of financing.

In practice, most firms operate under capital rationing. That is, managementimposes constraints that keep the capital expenditure budget below optimal (whereIRR�ka). Because of this, a gap frequently exists between the theoretically optimalcapital budget and the firm’s actual level of financing/investment.

S U M M A RYFOCUS ON VALUE

The cost of capital is an extremely important rate of return used by the firm in the long-term decision process, particularly in capital budgeting decisions. It is the expected averagefuture cost to the firm of funds over the long run. Because the cost of capital is the pivotalrate of return used in the investment decision process, its accuracy can significantly affectthe quality of these decisions.

Even with good estimates of project cash flows, the application of NPV and IRR deci-sion techniques, and adequate consideration of project risk, a poorly estimated cost of capi-tal can result in the destruction of shareholder value. Underestimation of the cost of capital


can result in the mistaken acceptance of poor projects, whereas overestimation can causegood projects to be rejected. In either situation, the firm’s action could be detrimental to thefirm’s value. By applying the techniques presented in this chapter to estimate the firm’s costof capital, the financial manager will improve the likelihood that the firm’s long-term deci-sions are consistent with the firm’s overall goal of maximizing stock price (owner wealth).

REVIEW OF LEARNING GOALS

Understand the key assumptions that underliecost of capital, the basic concept of cost of capi-

tal, and the specific sources of capital that itincludes. The cost of capital is the rate of returnthat a firm must earn on its investments to maintainits market value and attract needed funds. It isaffected by business and financial risks, which areassumed to be unchanged. To capture the interrelat-edness of financing, a weighted average cost of capi-tal should be used to find the expected averagefuture cost of funds over the long run. The specificcosts of the basic sources of capital (long-term debt,preferred stock, retained earnings, and commonstock) can be calculated individually.

Determine the cost of long-term debt and thecost of preferred stock. The cost of long-term

debt is the after-tax cost today of raising long-termfunds through borrowing. Cost quotations, calcula-tion (using either a trial-and-error technique or a fi-nancial calculator), or an approximation can beused to find the before-tax cost of debt, which mustthen be tax-adjusted. The cost of preferred stock isthe ratio of the preferred stock dividend to thefirm’s net proceeds from the sale of preferred stock.The key formulas for the before- and after-tax costof debt and the cost of preferred stock are given inTable 11.4.

Calculate the cost of common stock equity andconvert it into the cost of retained earnings and

the cost of new issues of common stock. The cost ofcommon stock equity can be calculated by using theconstant-growth valuation (Gordon) model or theCAPM. The cost of retained earnings is equal to thecost of common stock equity. An adjustment in thecost of common stock equity to reflect underpricingand flotation costs is necessary to find the cost ofnew issues of common stock. The key formulas forthe cost of common stock equity, the cost of re-

Calculate the weighted average cost of capital(WACC) and discuss the alternative weighting

schemes. The firm’s WACC reflects the expectedaverage future cost of funds over the long run. Itcan be determined by combining the costs of spe-cific types of capital after weighting each of them byits proportion using historical book or market valueweights, or target book or market value weights.The theoretically preferred approach uses targetweights based on market values. The key formulafor WACC is given in Table 11.4.

Describe the procedures used to determinebreak points and the weighted marginal cost of

capital (WMCC). As the volume of total new fi-nancing increases, the costs of the various types offinancing will increase, raising the firm’s WACC.The WMCC is the firm’s WACC associated with itsnext dollar of total new financing. Break points rep-resent the level of total new financing at which thecost of one of the financing components rises, caus-ing an upward shift in the WMCC. The general for-mula for break points is given in Table 11.4. TheWMCC schedule relates the WACC to each level oftotal new financing.

Explain how the weighted marginal cost of cap-ital (WMCC) can be used with the investment

opportunities schedule (IOS) to make the firm’sfinancing/investment decisions. The IOS presents aranking of currently available investments from best(highest return) to worst (lowest return). It is usedin combination with the WMCC to find the level offinancing/investment that maximizes owner wealth.The firm accepts projects up to the point at whichthe marginal return on its investment equals itsweighted marginal cost of capital.

SELF-TEST PROBLEM (Solution in Appendix B)

ST 11–1 Specific costs, WACC, WMCC, and IOS Humble Manufacturing is interestedin measuring its overall cost of capital. The firm is in the 40% tax bracket. Cur-rent investigation has gathered the following data:

Debt The firm can raise an unlimited amount of debt by selling $1,000-par-value, 10% coupon interest rate, 10-year bonds on which annual interest pay-ments will be made. To sell the issue, an average discount of $30 per bond mustbe given. The firm must also pay flotation costs of $20 per bond.

Preferred stock The firm can sell 11% (annual dividend) preferred stock at its$100-per-share par value. The cost of issuing and selling the preferred stock isexpected to be $4 per share. An unlimited amount of preferred stock can be soldunder these terms.

Common stock The firm’s common stock is currently selling for $80 per share.The firm expects to pay cash dividends of $6 per share next year. The firm’s div-idends have been growing at an annual rate of 6%, and this rate is expected tocontinue in the future. The stock will have to be underpriced by $4 per share,and flotation costs are expected to amount to $4 per share. The firm can sell anunlimited amount of new common stock under these terms.

Retained earnings The firm expects to have $225,000 of retained earningsavailable in the coming year. Once these retained earnings are exhausted, thefirm will use new common stock as the form of common stock equity financing.

a. Calculate the specific cost of each source of financing. (Round to the nearest0.1%.)

b. The firm uses the weights shown in the following table, which are based ontarget capital structure proportions, to calculate its weighted average cost ofcapital. (Round to the nearest 0.1%.)

(1) Calculate the single break point associated with the firm’s financial situa-tion. (Hint: This point results from the exhaustion of the firm’s retainedearnings.)

(2) Calculate the weighted average cost of capital associated with total newfinancing below the break point calculated in part (1).

(3) Calculate the weighted average cost of capital associated with total newfinancing above the break point calculated in part (1).

11–16 Calculation of specific costs, WACC, and WMCC Lang Enterprises is inter-ested in measuring its overall cost of capital. Current investigation has gatheredthe following data. The firm is in the 40% tax bracket.

Debt The firm can raise an unlimited amount of debt by selling $1,000-par-value, 8% coupon interest rate, 20-year bonds on which annual interestpayments will be made. To sell the issue, an average discount of $30 per bond would have to be given. The firm also must pay flotation costs of $30 per bond.

Preferred stock The firm can sell 8% preferred stock at its $95-per-share par value. The cost of issuing and selling the preferred stock is expected to be $5 per share. An unlimited amount of preferred stock can be sold under theseterms.

Common stock The firm’s common stock is currently selling for $90 per share.The firm expects to pay cash dividends of $7 per share next year. The firm’sdividends have been growing at an annual rate of 6%, and this is expected tocontinue into the future. The stock must be underpriced by $7 per share, andflotation costs are expected to amount to $5 per share. The firm can sell anunlimited amount of new common stock under these terms.

Retained earnings When measuring this cost, the firm does not concern itselfwith the tax bracket or brokerage fees of owners. It expects to have available$100,000 of retained earnings in the coming year; once these retained earningsare exhausted, the firm will use new common stock as the form of commonstock equity financing.

CHAPTER 11 CASE Making Star Products’ Financing/Investment Decision

Star Products Company is a growing manufacturer of automobile accessorieswhose stock is actively traded on the over-the-counter exchange. During

2003, the Dallas-based company experienced sharp increases in both sales andearnings. Because of this recent growth, Melissa Jen, the company’s treasurer,wants to make sure that available funds are being used to their fullest. Manage-ment policy is to maintain the current capital structure proportions of 30%long-term debt, 10% preferred stock, and 60% common stock equity for at leastthe next 3 years. The firm is in the 40% tax bracket.

Star’s division and product managers have presented several competinginvestment opportunities to Ms. Jen. However, because funds are limited,choices of which projects to accept must be made. The investment opportunitiesschedule (IOS) is shown in the following table.

Financing Cost DataStar Products Company

Long-term debt: The firm can raise $450,000 of additional debt by sell-ing 15-year, $1,000-par-value, 9% coupon interest rate bonds that payannual interest. It expects to net $960 per bond after flotation costs. Anydebt in excess of $450,000 will have a before-tax cost, kd, of 13%.

Preferred stock: Preferred stock, regardless of the amount sold, can beissued with a $70 par value and a 14% annual dividend rate and will net$65 per share after flotation costs.

Common stock equity: The firm expects dividends and earnings pershare to be $0.96 and $3.20, respectively, in 2004 and to continue togrow at a constant rate of 11% per year. The firm’s stock currently sellsfor $12 per share. Star expects to have $1,500,000 of retained earningsavailable in the coming year. Once the retained earnings have beenexhausted, the firm can raise additional funds by selling new commonstock, netting $9 per share after underpricing and flotation costs.
